CEILING, FLOOR, AND ROOF CONSTRUCTION Application filed October 20,1928. Serial No. 313,799.

This invention relates to the construction of the ceilings, floors androofs of buildings; and the object of the invention is to provide aconstruction of this class consisting ofa 4 t plurality of sheet metalsections adapted to extend from wall to wall or from a beam arrangedcentrally of a room to opposite walls thereof, the side edges of saidsections interlocking, and said sections forming the surface of theceiling and being preferably ribbed to form a beamed ceiling effect; afurther object being to provide reinforcing members employed inconjunction with said sections to reinforce the body of concretearranged within and above the same, said body of concrete forming thefloor surface or the support for the roof structure of a building or thetiles or other facings employed in conjunction therewith; a furtherobject being to provide a central beam in connection with which saidsections and reinforcing members operate, said central beam beingfashioned to receive said sections and reinforcing members as well asthe body of '25 concrete employed; and with these and other objects inview, the invention consists in a structure of the class and for thepurpose specified which is simple in construction, eflicient in use, andwhich is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Fig. 1 is a perspective view showingpart of the upper floor and roof structure of a building andillustrating the manner of con structing said floor and roof.

Fig. 3 is a partial section on the line 33 of Fig. 2.

Fig. 4 is a plan View of a part of the structure shown in Fig. 1 on anenlarged scale; and,

Fig. 5 is a plan view of one of a number of sections which I employ withpart of the construction broken away.

For the purpose of illustrating one method of carrying my invention intoeffect, I have shown at 10 in Fig. 1 of the drawings, the upper floor ofa building which also forms the ceiling for the floor below. At 11 Ihave shown a roof structure which may also constitute the ceiling of theupper floor. In practice, I employ a plurality of sheet metal sections12 which may be of a length sufficient to extend from one wall to theopposite wall of a room or from one wall to a central beam 13 in themanner shown in the accompanying drawings. 7

The beam 13 is fashioned from a comparatively heavy gage of metal suchas employed in the construction of steel beams or girders and consistsof a vertical wall 14, oppositely extending lower walls 15 whichterminate in upwardly extending flanges 16, note Fig. 2 of the drawings.Employed in con- 7 junction with the beam 13 is a facing member 18 ofcomparatively thin metal which is arranged upon the lower face of thewalls 15 and extends upwardly at the outer faces of the flanges 16andabove said flanges, the same being cut at intervals and fashioned toform inwardly directed tongues 19 between which are upwardly directedtongues 20. The tongues 19 rest upon the upper edges of the flanges 16and serve to hold the facing 18 in position.

The sheet metal sections 12 are fashioned to provide at one end alongitudinal rib 21 which is U-shaped in cross sectional form, thechannel of said rib being directed up- 35 wardly forming a beamed eifectat the lower surface of said section, and a similar rib 22 is arrangedsubstantially centrally of the section, whereas the other side of saidsection is provided with a downwardly turned flange 23 which is adaptedto enter the 1 channel of the rib21 of an adjacent section 12 in themanner clearly seen in Fig.

3 of the drawings.

The ribs 21 and 22 at one end of the sections 12 are adapted to seat inthe recesses formed by the inwardly and downwardly turned tongues 19 andto rest upon said tongues as clearly seen in Fig. 2 of the drawings. Thetop wall of the sections 12 adjaits cent said end and between the ribs21 and 22 and the rib 22 and flange 23 is cut out as seen at 24f toleave a space or opening between said ends of the sections and thevertical wall 14 of the beam 18 to permit the pouring of concretedownwardly into the channels of said beam inwardly of the flanges 16 aswill be apparent.

The other or lower end of the sections 12, in the construction shown, isfashioned intermediate the side walls of the ribs 21, 22, and the flange23, to form downwardly extending wall portions 25 and outwardlyextending flanges 26 which rest upon the wall beams or other supports 27The wall portions 25 serve to hold the concrete in proper position atsaid ends of the sections and also to finish the ceiling structure withthe wall structure of the building, as will be apparent. The said lowerend of the ribs 21 and 22 are bent slightly so as to seat properly uponthe support 27.

In this connection, it will be understood that the upwardly directedtongues 20 extend into the recesses formed at the other end of thesections 12 between the top wall of said sections and the walls of theribs 21 and 22 and take the place of the Wall portions 25 as Will beapparent.

It will be understood that the ribs 21 and 22 of the sections 12 when acomplete floor and ceiling structure has been formed, form the facing ofthe ceiling and what may be termed a beamed effect in conjunction withthe central beam when the same is employed. However, when this beam isnot employed, both ends of the sections 12 will be formed similar to theend provided with the wall members 25 thereon.

Employed in conjunction with the sections 12 are reinforcing members 28consisting of comparatively heavy rods folded centrally to form adjacentparallel rod members 28a adapted to be arranged in one of the channelsformed by the ribs 2122 and to extend longitudinally of said ribs fromone end of the section to the other and are then bent laterally inopposite directions to form parts 28?) adapted to be arranged adjacentthe wall portions 25 and in notches 29 formed in the side walls of theribs 21 and'22 at said end of said sections and then extend backwardlythrough the channels of the next adjacent ribs as seen at 280 note Fig.4.

The ends 280 and the central portion formed by the parallel rods 28a arefashioned at their ends to form hook members 28d adapted to rest uponthe upper edge of the vertical wall 14 of the beam 18, note Fig. 2 ofthe drawings and this serves to support said rods in proper position andalso maintains the reinforcement in firm engagement with the supportingbeam 13 which may constitute the ridge beam of a building.

The members 28 also serve to reinforce the body of concrete designatedat 30 which is poured onto the coupled sections 12 and the beam 13 aswell as upon the outer wall beams or supports 27 in forming the finishof the floor or roof structure, the concrete being poured to a levelabove the upper faces of the sections 12 and the beam 13 as will beapparent.

In forming a roof structure which is preferably inclined asdiagrammatically illustrated, slates, tiles or the like 31 may be setinto or partially imbedded in the concrete prior to the setting of thesame, and in the operation of forming the roof structure, to provide afinish thereto other than the concrete finish if the same is desiret.

When the concrete has been poured and the entire ceiling, floor or roofstructure completed, it will be understood that this concrete isarranged within the ribs 21--22 and forms thereof concrete beams ofwhich the sections 12 constitute merely a facing which may be painted orotherwise ornamented or decorated to give the desired ceiling effect,the distance between the ribs being governed solely and primarily by thedesired effect to be produced, and this is also true of the particularcross sectional form or contour thereof. It will also be understood thatthe sections 12 may bearranged in any desired relation at opposite sidesof the central beam 13 and any suitable arrangement of the reinforcingmembers 18 may be employed and in fact other reinforcementthan thatshown may be employed if desired.

In assembling the various sections and reinforcing members, it ispreferred that the members 28 be coupled with each section prior toplacing the same in position, or the outer ends of the sections may beraised after their assemblage in order to place the parts 286 in therecesses 29 as will be apparent. On the other hand, sufficient clearancemay be allowed between the ends of said sections and theadjacentbuilding wall or support to allow for the passage of the parts 286 ofthe members 28 into position as is indicated in dotted lines of Fig.

2 of the drawings.

l/Vith my improved ceiling, floor and roof construction, it will beunderstood that the cost of constructing ceilings, floors and roofs ofbuildings may be materially reduced in the saving of labor heretoforerequired in placing the usual floor beams and the like in position, andfurther in eliminating all plastering and similar operations which is acommon practice; and in addition to the saving of manual labor, a savingin material is also effected and the resulting structure is renderedfireproof.

It will also be apparent that my invention is not necessarily limited tothe use of sections 12 of any limited length or width, it beingunderstood that any number of the ribs 21-22 may be employed, but it ispreferred to construct these sections of such dimensions as tofacilitate the handling thereof both from the standpoint of shipment andhaulage as well as from the standpoint of placing the same in positionin the construction of a building, and various other changes in andmodifications of the construction herein shown and described may be madewithin the scope of the appended claims without departing from thespirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is
